UNITED STATES PATENT OFFICE.

ELIZABETH M. PORTER, OF GREENE, NEW YORK.

To all whom t may concern.'

Be it known that I, ELIZABETH M. PORTER, a citizen of the United States, residing at Greene, in the county of Chenango and State of New York, have invented certain new and useful Improvements in Oven- Mats, of which the following is a specification.

My invention relates to an improvement in oven mats in which a mat formed with a non-conducting surface is provided to be used in ovens 0r other heated places, for the purpose of protecting bake stuii's from being burned during the process of baking, and it has for an object to provide a light, adjustable mat having a surface composed of nonconducting material,`rigidly supported by a frame or other back, and to be easily manufactured and easily adapted to different kinds of ovens.

With this object in view my invention consists in certain novel features of construction and arrangement of parts as. will be hereinafter fully described and pointed out in the claim, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my device" as applied to bake stuffs in an oven. Fig. 2 is a top plan view of my device. Fig. 3 is a sectional view of my device taken on line 3. 3 of Fig. 2. Fig. 4: is a top plan view of my device in which the top is perforated. Fig. 5 is a sectional view of my device with perforated top taken on line 5. V5 of Fig. 4. Fig. 6 is a longitudinal section of a modified form of my device taken on the line 6. 6 of Fig. 7, and Fig. 7 is a cross section taken on the line 7. 7 of Fig. 6.

In carrying out my invention, I provide a top surface, A comprised of metal, having overlapping edges, B, B. Beneath the top A and fastened to it by the overlapping edges B, B I have a layer of asbestos paper or other non-conducting material C. Mounted in each end of the top A, I have the rings 0l, d. These rings permit ready manipulation of the mat and also aord means whereby the mat may be suspended from the oven shelf, if desired. The top A may be perforated forming an open frame work A with the cross bars A as shown in Fig. 4, and mounted on the lower side of Specification of Letters Patent.

Application led March 5, 1913.

Serial N o. 752,041.

the same I have a layer of asbestos C, or other non-conducting material.

In a modified form of my device I have the top support surface, A formed in two parts, A', A2, part A slidingover the part A2. Part A2 has projecting from it the bent guides a', sv, which are bent over the ends of the part A to permit the part A to slide relative to the part A2 and prevent separation of the parts. Part A has projecting from its upper surface at the inner end, the lugs y, y, contacting with the bent lugs, fc, m when the part A is pulled out from over the part A2, thus limiting the extension of the parts. By these means the part A is held in a slidable position over part A2, and the entire body A can be varied in length by sliding the parts, one over the other, and is thus better adapted to dierent sized ovens and for different purposes.

In operation I place the mat with the non-heat conducting surface, downward upon the bake stu in the oven. It prevents the materials from becoming burned or blackened by the excessive heat at the top while being baked within their respective receptacles, and thus enables the entire article to be baked evenly throughout.

Having thus described my invention, what I claim as new and for which I desire Letters Patent is as follows:

An eXtensible oven mat comprising upper and lower parts, each formed of a nonconducting sheet and a metallic frame disposed above said sheet, with the end and side edges of the frame bent to over-lap the nonconducting sheet to hold the sheet and frame together, guide lugs carried by the lower part and bent to over lap the upper part but permitting a sliding movement between the parts, and stop lugs carried by the upper part for coperating with the guide lugs to limit the extension of the parts.

In testimony whereof I have aiiiXed my signature in presence of two witnesses.
